  • Blood Vessels
    BLOOD VESSELS Blood vessels are how blood travels through the body. Whole blood is a fluid made up of red blood cells (erythrocytes), white blood cells (leukocytes), platelets (thrombocytes), and plasma. It supplies the body with oxygen. SUPERIOR AORTA (AORTIC ARCH) VEINS & VENA CAVA ARTERIES There are two basic types of blood vessels: veins and arteries. Veins carry blood back to the heart and arteries carry blood from the heart out to the rest of the body. Factoid! The smallest blood vessel is five micrometers wide. To put into perspective how small that is, a strand of hair is 17 micrometers wide! 2 BASIC (ARTERY) BLOOD VESSEL TUNICA EXTERNA TUNICA MEDIA (ELASTIC MEMBRANE) STRUCTURE TUNICA MEDIA (SMOOTH MUSCLE) Blood vessels have walls composed of TUNICA INTIMA three layers. (SUBENDOTHELIAL LAYER) The tunica externa is the outermost layer, primarily composed of stretchy collagen fibers. It also contains nerves. The tunica media is the middle layer. It contains smooth muscle and elastic fiber. TUNICA INTIMA (ELASTIC The tunica intima is the innermost layer. MEMBRANE) It contains endothelial cells, which TUNICA INTIMA manage substances passing in and out (ENDOTHELIUM) of the bloodstream. 3 VEINS Blood carries CO2 and waste into venules (super tiny veins). The venules empty into larger veins and these eventually empty into the heart. The walls of veins are not as thick as those of arteries. Some veins have flaps of tissue called valves in order to prevent backflow. Factoid! Valves are found mainly in veins of the limbs where gravity and blood pressure VALVE combine to make venous return more 4 difficult.

  • Superior Vena Cava Syndrome
    23 Superior Vena Cava Syndrome Francesco Puma and Jacopo Vannucci University of Perugia Medical School, Thoracic Surgery Unit, Italy 1. Introduction 1.1 Anatomy The superior vena cava (SVC) originates in the chest, behind the first right sternocostal articulation, from the confluence of two main collector vessels: the right and left brachiocephalic veins which receive the ipsilateral internal jugular and subclavian veins. It is located in the anterior mediastinum, on the right side. The internal jugular vein collects the blood from head and deep sections of the neck while the subclavian vein, from the superior limbs, superior chest and superficial head and neck. Several other veins from the cervical region, chest wall and mediastinum are directly received by the brachiocephalic veins. After the brachiocephalic convergence, the SVC follows the right lateral margin of the sternum in an inferoposterior direction. It displays a mild internal concavity due to the adjacent ascending aorta. Finally, it enters the pericardium superiorly and flows into the right atrium; no valve divides the SVC from right atrium. The SVC’s length ranges from 6 to 8 cm. Its diameter is usually 20-22 mm. The total diameters of both brachiocephalic veins are wider than the SVC’s caliber. The blood pressure ranges from -5 to 5 mmHg and the flow is discontinuous depending on the heart pulse cycle. The SVC can be classified anatomically in two sections: extrapericardial and intrapericardial. The extrapericardial segment is contiguous to the sternum, ribs, right lobe of the thymus, connective tissue, right mediastinal pleura, trachea, right bronchus, lymphnodes and ascending aorta.

  • Superior Vena Cava Stent Insertion
    Superior Vena Cava Stent Insertion This leaflet tells you about the procedure for inserting a vena cava stent. It explains what will happen before, during and after the procedure, and explains what the possible risks are. What is a vena cava stent? The superior vena cava (SVC) is the large vein that carries blood from the head, neck and arms back to the heart. If this vein becomes obstructed (narrowed) or blocked it can result in swelling of the face and arms, headaches and breathlessness. An SVC stent is a metal mesh tube that is placed inside the vein to hold it open and improve blood flow. The stent should result in a rapid improvement in your symptoms. What will happen before the procedure? The radiologist (specialist x-ray doctor) who will carry out the procedure will explain what he is going to do and you will have the opportunity to ask any questions that you may have. A nurse will look after you throughout the procedure and there will also be a radiographer present who will operate the x-ray equipment. You will be asked to lie on your back on the x-ray couch. You will have a monitoring device attached to your chest and finger, and your blood pressure will be checked regularly during the procedure. It is important that everything is kept sterile, so your body will be draped with sterile towels. The radiologist will wear a theatre gown and gloves. You will be awake throughout the procedure. The stent will be inserted through a vein in your groin.

Ohta) With 8 Figures in 2 Plates and 2 Tables -Received for Publication, July 24, 1971- A case of the so-called bilateral superior venae cavae after the persistence of the left superior vena cava has appeared relatively frequent. The present authors would like to make a report on such a persistence of the left superior vena cava, which was found in a routine dissection cadaver of their school. This case is accompanied by other anomalies on the venous system ; a complete pair of the azygos veins, the double subclavian veins of the right side and the ring-formation in the left external iliac vein. Findings Cadaver : Mediiim nourished male (Japanese), about 157 cm in stature. No other anomaly in the heart as well as in the great arteries is recognized. The extracted heart is about 350 gm in weight and about 380 ml in volume. A.

The result- ing increased venous pressure in the upper body may cause edema of the head, neck, and upper extremities, often associated with cyanosis, plethora, and distended subcutaneous vessels. Despite the often striking clinical presentation, SVCS itself is usually not a life-threatening condition. Currently, randomized controlled trials on many clinically important aspects of SVCS are lacking. This review gives an interdisciplinary overview of the pathophysiology, etiology, clinical manifes- tations, diagnosis, and treatment of malignant SVCS.

Recurrent venous thrombosis is typically associated with a hypercoagulable state such as malignancy, and inheritable or acquired coagulopathy. Sarcoidosis is a derangement of the immune system, and it has been associated with malignant diseases and hypercoagulation. The association of pancreatic cancer and sarcoidosis with SVC syndrome has not been reported previously. Here, we present a case of recurrent venous thrombosis causing SVC syndrome in a patient with pancreatic ductal adenocarcinoma and underlying thoracic sarcoidosis.

  • Azygos Vein Cannulation: Recognition Is Vital for Preventing Complications
    CASE REPORTS Azygos vein cannulation: recognition is vital for preventing complications Ragesh Panikkath MD, Sian Yik Lim MD, Deepa Panikkath MD ABSTRACT Inadvertent cannulation of the azygos vein can occur during central vein cannulations, especially from the left side. This can cause several complications, including rupture of the azygos vein. This complication is unlikely from the more commonly used right inter- nal jugular vein access, although that approach is not free of complications. An abrupt curve at the tip of the central venous catheter showing venous wave forms and high oxygen saturations suggest azygos vein cannulation. Azygos vein cannulations may be more common in patients with heart failure in which the vein is dilated.
